    For all u fx 5800 users

    Ok, heres some of my work for you guys

    The Vcore mod is done using a 50kohm variable resistor set to 0 ohm. You increase the vcore by increasing the resistance. As you can see you connect the resistor pins to the black and white cable. There should be a 0 resistor there, you have to unsolder it

    The stock voltage is:
    1.1V in 2d
    1.35V on rev. M cards in 3d
    1.45V on rev. H cards in 3d

    The Vddr mod is something like a Vdd mod on a Radeon 8500/9xxx

    I used a 50kohm Variable resistor set to 50k, the second pin is connected to ground. You increase the voltage by decreasing resistance. The stock voltage is:
    2.5 to 2.55V on rev. H cards
    2.6 to 2.65V on rev. M cards

    And what about the stock voltages on Rev. J ?
    Can you tell me where the measure points are?

    Two questions:

    What voltage do I get on the core with the mod?
    I have a rev J by the way.

    Second, by changing the bios I can up my memory, but do you know if it's just worse timings or that you actually get higher voltage or something?
    Have you looked at your score at the same speeds using original bios and the ultra one?

    ---------------------------------------------------------------

    The capacitors on top right are for Vcore, on the bottom righ are for Vddr

    Im still working on the remaining Vmods


    too bad my old card is dead, it would OWN everything we've got (585/1170 clocks on a funny air cooler, no mods)


    --------------------------------------------------------------

    now it is only try to reach me friends
